For modern embedded systems in the realm of high-throughput multimedia, imaging, and signal processing, the complexity of embedded applications has reached a point where the performance requirements of these applications can no longer be supported by embedded system architectures based on a single processor. Thus, the emerging embedded system-on-chip(More)
Current emerging embedded System-on-Chip platforms are increasingly becoming multiprocessor architectures. System designers experience significant difficulties in programming these platforms. The applications are typically specified as sequential programs that do not reveal the available parallelism in an application, thereby hindering the efficient mapping(More)
Daedalus is a system-level design flow for the design of multiprocessor system-on-chip (MP-SoC) based embedded multimedia systems. It offers a fully integrated tool-flow in which design space exploration (DSE), system-level synthesis, application mapping, and system prototyping of MP-SoCs are highly automated. In this paper, we describe our first industrial(More)
The increasing complexity of modern embedded streaming applications imposes new challenges on system designers nowadays. For instance, the applications evolved to the point that in many cases hard-real-time execution on multiprocessor platforms is needed in order to meet the applications' timing requirements. Moreover, in some cases, there is a need to run(More)
In this paper, we present the Daedalus framework, which allows for traversing the path from sequential application specification to a working MP-SoC prototype in FPGA technology with the (parallelized) application mapped onto it in only a matter of hours. During this traversal, which offers a high degree of automation, guidance is provided by Daedalus'(More)
Emerging embedded System-on-Chip (SoC) platforms are increasingly becoming multiprocessor architectures. The advances in the FPGA chip technology make the implementation of such architectures in a single chip feasible and very appealing. Although the FPGA chip technology is well developed by companies such as Xilinx and Altera, the concepts and the(More)
We use the polyhedral process network (PPN) model of computation to program embedded Multi-Processor Systems on Chip (MPSoCs) platforms. If a designer wants to reduce the number of processes in a network due to resource constraints, for example, then the process merging transformation can be used to achieve this. We present a compile-time approach to(More)

The Process Network (PN) is a suitable parallel model of computation (MoC) used to specify embedded streaming applications in a parallel form facilitating the efficient mapping onto embedded parallel execution platforms. Unfortunately, specifying an application using a parallel MoC is very difficult and highly error-prone task. To overcome the associated(More)
